The Big Damn Heroes moment of Seira, Luna, and Ginka deserves credit. Not only did they save Akari from being killed but also a wonderful teamwork was performed.
Fairly substantial here is that Akari helping people around her? Yes!
Two words: More Dakka courtesy by Seira Hoshikawa.
When the big reveal is presented to Akari, Namely her being half Daemonia she immediately decides that she could make good use of this to help others. It really shows how courageous she is, and how determined she is to change the terrible circumstances surrounding her.
